They really should make these boxes safer.I can imagine a child trying to crawl in there , a few kids playing aorund and hoisting a little kid in there.
We now have the injunction to remove doors off regrigerators before being placed on the curb for pick-up for that very reason.
This law was put into place because the old refrigerators had latches that locked the door and kept it from being opened from the inside. Today's fridges all use magnetic closures that DO NOT lock the door, this is a safety feature that makes leaving a fridge with the door on as safe as one without the door.
As for placing one more law on the books because someone might be stupid enough to crawl inside one of these boxes, especially since it hasn't happened except to an extremely greedy woman, is just advocating for more nanny state laws.
